Your wife has expressed that you have a certain fetish she doesn't particularly like. It is a deal breaker for her and you have the choice to try and break this fetish, or she will leave you. We can start the therapy straight away. It's simple, I shrink you down and you swallow my farts til it disgusts you and you no longer like farts. You don't want your wife to leave you right? You don't want to have your wife married to a loser who enjoys swallowing farts right?
